T0 at whom it may concern;

Be it known that I, JOSEPH K6NIG, watchmaker, a subject of the Grand Duke of Baden, residing at Gaggenau, in the Grand Duchy of Baden and German Empire, have invented certain new and useful Improvements in Fumigators, of which the following is a specification.

My invention relates to a fumigator or apparatus for producing smoke, and is particularly intended for use in preventing bees from attacking the operator during his work at the hives. A form of constriiction of this apparatus is represented in the accompanying drawings, in which Figure 1 is an elevation of the apparatus; Fig. 2, a vertical section; Fig. 3, a cross-section on the line A B, Fig. 1; and Fig. 4 is a detail view.

A clock or like spring 17, driving a fan or blower c, is arranged in the sheet-metal casing a. The airis propelled by the fan 0 through a nozzle d, into the smoke-chamber 6, provided near its lower part with a sieve-like bottomfand closed at the top with a sieve-like detachable cover g, so that a part of the air passes through the bottom f, thus maintaining the burning of the tobacco or the like, which is placed on the sieve f in the chamber h and ignited. The other part of the air, driven upward by the fan 0, passes through a pipe 1', vertically and centrally arranged in the smoke-chamber, and draws along with it as it issues the smoke from the chamber h, through the reticulate cover g, and thence through the pipe or nozzle 7c, so that the smoke escapes in the form of a strong jet through the vided with orifices 50, so as to enable the air entering through the same to cool the smokechamber 6. Afree space is provided for this purpose between the chambere and the perforated upper. part of the casing a.

The stopping-spindle Z of the clockwork b is provided with a lever 'm and with a wire n, to which latter a plate or flap 0 is attached for regulating or closing the air-supply open- The lever m serves also for arresting the clockwork, since a pin (not shown in the drawings) mounted upon the shaft Z, stops one of the wheels when the plate by means of the key 8 and the lever m, and

thereby the plate 0 turned into the position shown in full lines in Figs. 1 and 4, and the apparatus is ready for use.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. In a fumigator, a smoke-chamber having reticulated bottom and top, a pipe extending entirely through the smoke-chamber, and a fan and its casing below the smoke-chamber,-

the fan-casing having a nozzle located below the said reticulated bottom and said pipe.

2. In a fumigator, asmoke-chamber having reticulated bottom and top, a pipe extending entirely through the smoke-chamber, a fan and its casing, the fan-casing having a nozzle the delivery end of which is located below said reticulated bottom and pipe and said casing having an air-supply opening, and a manually-operable flap for regulating said airsupply opening.

3. In a fumigator, a smoke-chamber having a reticulated bottom and a movable reticulated top whereby smoke-producing devices can be introduced into said chamber by lifting the top, apipe passingthrough the smokechamber and means located below the smokechamber and said pipe for directing currents of air therethrough.

4. In afumigator, a smoke-chamber having a reticulated bottom a cover-piece hinged to said'chamber having a piece of reticulated material constituting a top for said smokechamber, a draft-pipe in cooperative relation with the smoke-chamber, and means for sending currents of air simultaneously through the smoke-chamberand draft-pipe.

5. In afumigator, asinoke-chamber having In testimony whereof I have hereunto set reticulated bottom and top, a pipe passing enmy hand in presence of two subscribing wit- 1o tirely through said smoke-lchamber, 21ml peigonesses. rated jacket surrounding t e smoke-c am er I 5 and separated therefrom by an air-space, and JOSEPH KONIG means for directing currents of air through \Vitnesses: the smoke-chamber and pipe from a place be- LEOPOLD KAUFMANN, low the same.
